Description

Technical Field

[0001] This utility model relates to a training device, more specifically a pipeline disassembly and assembly training device. Background Technology

[0002] Existing pipeline disassembly and assembly training devices cannot easily drain water from the pipes during student training, leading to significant water contamination of the disassembly and assembly site. For example, Chinese utility model patent document CN208969996U discloses a pump disassembly, assembly, and operation training device, as shown in Figure 4. The technical solution disclosed in this patent document cannot easily drain water from the pipes during student disassembly and assembly tests, easily contaminating the experimental site. Summary of the Invention

[0003] The purpose of this invention is to provide a pipeline disassembly and assembly training device. When students need to disassemble and assemble the pipeline, a portion of the water in the pipeline can be stored in the first water tank, and the other portion of the water in the pipeline can be discharged into the second water tank through the fourth valve. This avoids excessive water discharge into the training area during the disassembly and assembly process. After the disassembly and assembly are completed, the pump can pump the water stored in the second water tank back into the pipeline disassembly and assembly training device, thus avoiding water waste.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] The pipeline disassembly and assembly training device includes a second water tank. Pipeline disassembly and assembly training equipment is installed on the upper part of the second water tank. The equipment includes a pump. The pump outlet is connected to the inlet of a second valve. The outlet of the second valve is connected to the inlet of a fifth valve. The outlet of the fifth valve is connected to the inlet of a first water tank. The outlet of the first water tank is connected to the inlet of a seventh valve. The outlet of the seventh valve is connected to the inlet of the first valve. The outlet of the first valve is connected to the inlet of a check valve. The outlet of the check valve is connected to the inlet of an eighth valve. The outlet of the eighth valve is connected to the inlet of the pump. The eighth valve and the pump are connected via a guide pipe. The bottom of the guide pipe is connected to a third valve. The outlet of the third valve is connected to the inlet of a fourth valve. The inlet of the third valve is connected to an extension pipe. The lower end of the extension pipe extends to the inner bottom of the second water tank. A through-slot is formed in the upper part of the second water tank, and the outlet of the fourth valve is located above the through-slot.

[0006] To further achieve the purpose of this utility model, the following technical solution can also be adopted: the seventh valve and the first valve, the first valve and the check valve, and the check valve and the eighth valve are all connected by a guide pipe, and the end of the guide pipe closer to the pump is lower than the other end.

[0007] A pressure gauge is installed on the pipeline between the second valve and the pump, and the test end of the pressure gauge is connected to the pipeline between the pump and the second valve.

[0008] The upper part of the first water tank is connected to the inlet of the sixth valve.

[0009] The ninth valve is connected to the connecting pipe between the seventh valve and the first valve.

[0010] The advantages of this utility model are as follows: This utility model adds pipeline disassembly and assembly training equipment. When students need to disassemble and assemble the pipeline, the equipment can store part of the water in the pipeline into the first water tank, and the other part of the water in the pipeline can be discharged into the second water tank through the fourth valve. This avoids excessive water discharge into the training area during the disassembly and assembly process. After the disassembly and assembly is completed, the pump can pump the water stored in the second water tank back into the pipeline disassembly and assembly training equipment, thus avoiding water waste.

Detailed Implementation

[0017] The preferred embodiments of this utility model will be described below with reference to the accompanying drawings. Embodiment 1:

[0018] Pipeline disassembly and assembly training device, such as Figures 1-4As shown, the system includes a second water tank 11. A pipeline disassembly and assembly training device is installed on the upper part of the second water tank 11. This device includes a pump 5. The outlet of pump 5 is connected to the inlet of a second valve 6. The outlet of the second valve 6 is connected to the inlet of a fifth valve 12. The outlet of the fifth valve 12 is connected to the inlet of a first water tank 1. The outlet of the first water tank 1 is connected to the inlet of a seventh valve 14. The outlet of the seventh valve 14 is connected to the inlet of a first valve 2. The outlet of the first valve 2 is connected to the inlet of a check valve 3. The outlet of the check valve 3 is connected to the inlet of an eighth valve 16. The outlet of the eighth valve 16 is connected to the inlet of pump 5. The eighth valve 16 and pump 5 are connected via a guide pipe 15. The bottom of the guide pipe 15 is connected to a third valve 7. The outlet of the third valve 7 is connected to the inlet of a fourth valve 9. The inlet of the third valve 7 is connected to an extension pipe 8. The lower end of the extension pipe 8 extends to the inner bottom of the second water tank 11. A through-slot 10 is opened in the upper part of the second water tank 11, and the outlet of the fourth valve 9 is located above the through-slot 10.

[0019] This utility model adds a pipeline disassembly and assembly training device. When students need to disassemble and assemble the pipeline, the device can store part of the water in the pipeline into the first water tank 1, and the other part of the water in the pipeline can be discharged into the second water tank 11 through the fourth valve 9. This avoids excessive water discharge into the training area during the disassembly and assembly process. After the disassembly and assembly is completed, the pump 5 can pump the water stored in the second water tank 11 back into the pipeline disassembly and assembly training device, thus avoiding water waste.

[0020] Specific material selection and feasibility analysis: The samples we actually manufactured used the accompanying drawings as blueprints, implementing the process according to the proportions and fit methods of each component shown in the drawings. The connections employed included common methods such as strong adhesive bonding, welding, riveting, flange connections, and integral molding. During actual manufacturing, the appropriate connection method, thickness, and strength of the connection points could be selected based on the required connection strength without creative design. During the water circulation test, valves 7 (third), 9 (fourth), and 17 (ninth) were closed, while the other valves were open. Pump 5 was then activated, pumping water sequentially through valves 6 (second), 12 (fifth), 1 (first water tank), 14 (seventh), 2 (first), 3 (check valve), and 16 (eighth), before returning to pump 5. When students practice disassembly and assembly, they can first close valves 14 (seventh) and 16 (eighth), and open valves 13 (sixth) and 9 (fourth). Pump 5 will then pump a portion of the water in the pipeline to the first water tank 1 for storage. Next, close valve 12 and open valves 17 (ninth) and 16 (eighth). Valve 17 allows air to easily enter, facilitating the discharge of a small amount of water remaining in the guide pipe 15 through valve 9. Students can then practice disassembling and assembling valves 2 (first), 3 (check valve), and 16 (eighth). After completing the training, close valves 9 (fourth), 16 (eighth), and 17 (ninth), and open valve 7. Pump 5 will then pump the water pre-stored in the second water tank 11 back into the first water tank 1. Then, close valve 7 and open valve 16. The water circulation experiment can then be repeated. The volume of the first water tank 1 is larger than the volume of water in the pipeline disassembly and assembly training equipment.
